Telecom Switch Board and Jumper Wire
ATCPRO cables manufactures Telephone switch board cables. Let’s know about telephone wiring cables with a questionare:-
1. What Are Telephone Cables?
- Telephone cables transmit signals from one location to another.
- They consist of copper wires twisted together and insulated with a plastic coating to prevent interference and damage.
2. Color Coding Scheme:
- Telephone cables typically have multiple pairs of wires.
- The most common color coding scheme is the “tip” and “ring” system:
- Tip (Positive): One wire in the pair.
- Ring (Negative): The other wire in the pair.
3. Wiring Diagram for Standard Telephones:
- The wiring diagram shows how telephone jacks are connected.
- Components include:
- Red Wire: Connects to the tip (positive).
- Green Wire: Connects to the ring (negative).
- Blue and White Wire: Another pair for additional lines.
- White and Blue Wire: Yet another pair for more lines.
- Quick Fix Tip: If you get a dial tone but no tones when dialing, reverse the wire pair.
4. Installing a Telephone Wall Jack:
- Most wall phone jacks come configured for 2-line service (even for 1-line phones).
- Spare pairs can be used for additional lines or backup.
- Consider installing near an existing wall receptacle for low voltage transformers.
